It's not that material is ejected, it's that the heat radiates back out into space and acts as "thrust."

Seriously? So it's just radiated photons?
That means that we're talking of an effect that is so infinitesimal that we may never even be able to conclusively prove that it exists*, because it will be hugely overpowered by proven/provable effects.
Hell, you could equally say that the Earth's rotation and orbit are affected by the way it absorbs/reflects light, but the mass involved not only makes it impossible to prove, but also makes it unlikely to be true -- you exert a lot more force by slightly opening a tap (faucet) and letting water dribble into the sink.
* Except in abstract, of course, but I suppose that that's why numbers and "career mathematicians" exist.

Not necessarily.
The effect was first measured in 1991–2003 on the asteroid 6489 Golevka. The asteroid drifted 15 km from its predicted position over twelve years (the orbit was established with great precision by a series of radar observations in 1991, 1995 and 1999) from the Arecibo radio telescope.[3]

Good Lord! No sooner do I mention affirmation of the consequent in one posting, but I find an example of it in another posting! How synchrowhatzitous!
The thingy drifted 15 km, therefore it was caused by the Yarkovsky effect!
... Or maybe it hit a 3cc pebble, somewhere in the millions of miles that it travelled.

I'd never have looked up the following (Wikipedia) - but once I did it had to be posted. You must accept full responsibility for this.
Quote: Breeding season begins in late June and extends through September. Males will form lines up to ten individuals long, the youngest echidna trailing last, that follow the female and attempt to mate. During a mating season an echidna may switch between lines. This is known as the "train" system. Two weeks after mating, a single fertilized egg, weighing 380 milligrams and being about 1.4 centimetres long, is implanted in a rear-facing pouch that has developed on the female, where it is held for ten days before hatching. The young echidna, called a puggle, is then held in the pouch for two to three months before being expelled. Puggles will stay within their mother's den for up to a year before leaving
The males organ is also a thing of wonder (q.v.[^])

Today, I replaced my venerable, antiquated, near falling apart, ten year-old mouse and keyboard with a new LogiTech G910 kb, and a LogiTech G602 mouse. I almost feel I should bury the old kit with some kind of farewell ceremony in thanks for their long service.
I went for the G910 partly because, after trying various types of key-action mechanisms, I decided I liked the Romer-G switches more than I did the available models with Cherry MX switches, and (major factor) the Thai equivalent to NewEgg had a special on the 910 that made it substantially cheaper than other better-quality keyboards from Corsair, and other vendors. Of course, I studied the reviews of the different keyboards, trying to find reviews not written for hard-core gamers.
Adjusting to both will take some time; the mouse feels quite natural, the keyboard is requiring more attention to my fingers' (fast) speed-typing.
I'm not a gamer, and I wasn't aware of the fancy lighting capabilities of this keyboard, and I am rather amazed by them: but, why would I ever want my keyboard to run an animation where it cycles through the spectrum of colors moving from left to right across the keys ? Well, okay, that does save the cost of a lava-light, I guess 
Whether I'll find a use for nine dedicated macro-keys each of which can store 3 macros, is also ... uhhhh ... up in the air, as is whether I'll ever mess around with mouse's gamer features.
The one strange thing ... and, this keyboard did not come with an alternate set of Thai characters on the keyboard ... is that the keyboard maps the shifted quote key to produce the at-sign, and shifted 2 key to double-quote. And, shifted 3 produces the British Pound character. I've gone into Win 10 and checked that the Language is set to American English, not British. The tilde key produces: ` unshifted and ¬ shifted.
@It's like this when I try to use a double-quote, and C-Sharp becomes C£.@ The at-sign now: "
I'm sure I'll find some software trick to undo this re-mapping, perhaps by asking LogiTech a support question.
There is always a price to be paid when you ... upgrade, but, I'm not complaining ... yet.
cheers, Bill

Do you mean that SHIFT+3 gives £, and SHIFT+' (two right from "L") gives @ ?
If so, that's a UK layout. Which OS are you using?

I remember my favorite keyboard. I had a Tandy 1000 (8086) with a mechanical keyboard. It felt so great, I loved typing on it. I miss those days of typing away at the DOS prompt and programming in Turbo Pascal. 
Many respects to your old kit. 
When you are dead, you won't even know that you are dead. It's a pain only felt by others.
Same thing when you are stupid.

Yeah, I really liked mechanical keyboards. My first was a Teletype Model 15 attached to a homebrew 8080 system using the S-100 bus. When the keyboard got really dirty, we used to take it out of the teletype and run it through the rinse cycle of the dishwasher and re-oil it.

Your language is set to American English, but is your keyboard layout set that way? I think they're distinct settings.

Don't be tempted by the US International keyboard, it turns all your quote marks into accents.

As others have remarked, there are two distinct 'languages' at play - your machine will display in Mercan, but you need to set up your keyboard layout to Mercan too.
